.COMBINED -(JHU'BJIZI'NG' AND'I'EMULSIFYING C To all whom t may concern:

Be it known that l, Een; STEENBERG, manufacturer, o. 33, Jornsborvej, Hellerup, county of Copenhagen, Denmark, have invented certain new and useful improve.-

ments in Combined Churning and Emulsiiying Machines, of which the following 1s a specification.

p The resent invention relatesV to a machine rendering 1t practicable, at a certain temperature, pressure and counter-pressure, to churn and emulsif most intensively any liquid substance. t may be stated that a combined churning and emulsifyin ma'chine will be ,useful mainy in the manufacture of margarine, but also for other industrial purposes.

The invention is shown bn the drawing, Fig. 1 showing, Ain vertical longitudinal 2,0 section, a horizontally disposed construction of the machine, Y

. Fig. 3 a tightening device adapted to be used in the machine,

Fig. 4 an obliquely disposed construction of the machine, an v v Fig. 5 a vertically disposed construction. a indicates a cylindrical vessel in which and emulsifying .operation is performed. n order that the substance oontained in the vessel a may constantly be maintained at the temperature necessary for the favourable perfomance f the process a. is encircled by a jacket 'b 'with the necessary usual suppl` and discharge pipes not` shown on the awing, in such a manner that there .is provided a steam o1' water jacket outside of the vessel.

4 The vessel avis fitted with a supply hopper c'and a discharge tu valve e.- f VIn the end bottoms lof the vessel bearings are provided for a shaft f,- which is rotate `d with regulating Afeet will be attained an worm, the other leg of d Vjthan'in either of the;

servingsolely or has 'only a few holes, while the remainin portion, as rmentioned above is fitted wit holes h the shape, size andnumberof which are determined by the substance to churned or emulsied and by the pressure desired to be maintained in the vessel.

to transport the mass, is tight bed() When the shaft f is rotatediny the direction indicated by thearrow k 1n Fig. 1, the material which is filled into the vthe worm into portion of the tube, in the latter has become suiiciently, high, the said material will be pressed back through the holes h in the worm g, and as the worm is constantly rotated, the material will be in constantmotion, partl in the `intersti es along the threads of t ve worm and partly through the holes h. Hereby a very eiiicient emul'sfying and ychurning efmay, furthermore, be varied infinitely, the conditions depending merely on the rotary speed of the shaft, the pitch of the worm, the number and size of the holes and the diameter of the worm.

. Fig. 3 shows a packing device for the worm. This packing is used when the interstice between the worm and the vessel a is so large ythat there will be danger of too much of the churned material being pressed past the worm, and it consists of an L-shaped leather strip i attached to the edge of the the said strp sliding on the inside of the vessel a. Besi es or instead of the above mentioned holes h notches or incisions may be provided in the edge of the worm.v l

Fig. 4 shows an obliquely disposed machine by which the natural counter-pressure 'due to the liquids own weight will belarger than in the construction shown in Fig. 1. Fig. 5 shows a vertically disposed machine, in which the counter-pressure is still larger above mentioned constructions.

and 4when `the pressure fra 45- in the direction of the arrow k by means of suitable members. On-'this shaft there is provided a conveyor worm g` fitting quite closely against the inside of thecylinder and being provided with numerous small holes 5 in the spirals kor threads thereo as shown on the drawin The worm extends throughout the lengt and occupies the entire in-- terior space ofthe cylinder.

The worm g, on the'portion of the same 55 directly opposite the supply opening c and I' The machine may work with intermittent' as well as with continuous discharge, the valve e being first closed and the machine isthen sta 4ed` and filled, and works then until the churning and emulsifying operation is finished whereater the valve 'e is o ened and the machine emptied. t e machine isv'em tied, the valve is closed and themachine lled again. If the machine is to work continuously, it is filled 110 lng an inlet and while runnin and the valve e is adjusted until the desired vpressure inA the vessel has n attained. y

The discharge through this valve will then continuous.

As shown on Fig. 1 a return pipe may be applied from discharge-pipe d to the other end of the cylinder. c

` Patent claims:

1. Combined churnin and emulsifyi machine including a cylindrical vessel hava relativelysmall discharge located at an end opposite the inlet, a rotatably mounted perforated conveyor worm arranged within and extending throughout the length of the vessel and having its outer edges arranged in close relation to the'inner' surface of the vessel and operating in such a manner that the material is pressed towards the discharge end and is compacted at this end, and the worm in additioncreating' a high pressure to accelerate the emulsi- L g action, substantially vas and forl the purposes set forth.

2. Combined chuming and 'smuisifying A Y machine including va closed vcylindrical vesi sel, an inlet adjacent one end of the vessel, a relativel small valved control discharge plpe lea ing from the opposite end of the A mounted vessel, aconveyor worm rotatabl equal to within the vessel 'and of a lengt the length of the vessel, the spirals'of the worm being perforated and the outer edges of the spirals of the worm at this end under a relatively high pressure and thereby accelerate the emulsifying action.

3. Combined churning and emulsifyi 2 wherein the e discharge to machine as claimed in claim return `pipe extends \from th the inlet end of the machine.
